The New Noztek Nexus
The future of filament extrusion is here. Noztek is proud to announce the beta launch of our revolutionary Noztek Nexus extruder, representing a significant leap forward in precision extrusion technology that will transform how researchers and manufacturers approach material development.
Breaking New Ground with Servo Technology
After extensive research and development, we have constructed a prototype version of what we believe will become the new industry standard for precision filament extrusion. The Noztek Nexus represents our most ambitious engineering project to date, featuring a complete re imagining of extruder motor technology.
At the heart of this innovation lies our strategic transition from planetary motors to advanced servo motor systems We have replaced the traditional planetary motor configuration with a powerful 48V, 750W RS485 DC Servo Motor equipped with a 20:1 planetary gearbox. This sophisticated motor system operates at a maximum speed of 150 RPM while delivering an impressive 24 NM of torque.
The Science Behind the Switch
The decision to transition from conventional planetary motors to servo technology wasn’t made lightly. Our research into servo motor applications in precision manufacturing revealed compelling advantages that align perfectly with modern extrusion demands
.
Enhanced Precision Control: Servo motors provide exceptional positioning accuracy through their built-in feedback systems Unlike traditional planetary motors that operate in open-loop configurations, servo systems continuously monitor torque, speed, and position, creating what industry experts call a “comprehensive picture of the extrusion process”
.
Superior Speed Regulation: While planetary motors typically deliver reliable performance with ±5-10% speed variation, servo systems achieve speed regulation accurate to ±0.1%. Achieving a dramatic improvement in consistency directly translates to superior filament quality and dimensional accuracy.
Dynamic Torque Delivery: One of the most significant advantages of servo technology is its ability to maintain uniform torque across all speeds Traditional motors often experience torque reduction at higher speeds, but servo motors deliver consistent throughput even at 2000 RPM or higher
.
Real-Time Adaptability: Servo motors excel in applications requiring rapid dynamic response
They can quickly respond to changes in control signals, allowing for fast and precise adjustments during the extrusion process—a capability that’s crucial when working with varying material properties.
Combining Servo Power with Planetary Precision
Our engineering team recognized that while servo motors offer superior control, the addition of a planetary gearbox provides essential benefits for extrusion applications
Torque Amplification: The 20:1 planetary gearbox effectively multiplies the servo motor’s output torque by the gear ratio, allowing our 750W motor to handle the substantial forces required for consistent filament extrusion This torque multiplication is achieved while maintaining the servo’s precision control characteristics.
Load Distribution: Planetary gearboxes distribute transferred torque across multiple gear meshes simultaneously This load sharing among multiple teeth allows the system to transmit higher torque loads while maintaining exceptional durability and reducing wear on individual components.
Enhanced Stiffness: The high rotational stiffness provided by planetary systems minimizes elastic windup, which is crucial for applications requiring elevated positioning accuracy and repeatability This stiffness becomes particularly important under fluctuating loading conditions common in material extrusion.
Compact Power Density: Planetary gearboxes offer exceptional torque density in a compact design Which allows us to achieve substantial torque output while maintaining the Nexus’s manageable footprint and weight distribution.
Transformational Performance Results
Our initial testing has yielded remarkable results that validate our servo motor transition. In preliminary extrusion trials, the filament output performance nearly doubled, increasing from 2 meters per minute to an impressive 4.5 meters per minute. This dramatic improvement isn’t merely about speed—it represents a fundamental enhancement in process capability.
The added precision eliminates speed fluctuations that traditionally cause diameter variations in extruded filament. This consistency ensures uniform material properties throughout production runs, a critical factor for researchers developing new materials and manufacturers requiring tight tolerances.
Research-Grade Intelligence
The Nexus represents more than just a component upgrade—it’s a fundamental shift toward research-grade precision that will transform how our customers approach material development and filament production. The highly accurate motor encoder ensures smooth speed transitions while providing unprecedented process visibility
.
Real-Time Process Monitoring: The servo motor system provides continuous feedback on torque, speed, and position, creating comprehensive real-time data streams that researchers can use to optimize their processes This capability enables immediate process adjustments, eliminating waste of expensive specialty materials.
Advanced Data Analytics: Our integrated monitoring system will include real-time torque graphs and screw wear analysis, providing operators with detailed insights into the extrusion process. These analytics help identify optimal processing windows and predict maintenance requirements before issues impact production.
Intelligent Material Adaptation: The Nexus will feature a comprehensive library of preprogrammed settings optimized for major polymer families. These settings automatically adjust speed and torque parameters based on material properties, reducing setup time and ensuring optimal processing conditions for each application.
Mechanical Excellence Through Design
Beyond the motor transformation, the Nexus features significant mechanical improvements that enhance overall system performance and usability.
Robust Motor Integration: We’ve developed a new robust motor bracket, bearing assembly, and coupling system that significantly improves the centralization of the barrel and screw assembly. This enhanced alignment eliminates the need for a front bracket while making barrel removal substantially easier for cleaning and maintenance procedures.
Streamlined Maintenance: The improved mechanical design prioritizes user accessibility. Barrel removal for cleaning becomes much simpler, reducing downtime and maintenance complexity. This design philosophy reflects our understanding that research environments require equipment that can be quickly reconfigured for different materials and applications.
Enhanced User Interface: We are designing a new chassis featuring a 7-inch touchscreen interface to accommodate the increased number of menu options and control parameters that the servo system enables. This expanded interface will provide intuitive access to the advanced monitoring and control capabilities that set the Nexus apart from conventional extruders.
The Future of Extrusion Technology
The Noztek Nexus represents our vision for the future of precision filament extrusion. By combining advanced servo motor technology with intelligent planetary gearing, we’ve created a system that addresses the evolving needs of materials research and specialty manufacturing.
Industry-Leading Precision: The integration of servo technology with planetary gearing delivers positioning accuracy within micrometers while maintaining the robust torque output required for consistent material processing
.
Process Optimization: Real-time monitoring capabilities enable immediate process adjustments based on material behavior, ensuring optimal processing conditions and minimal waste. This capability is particularly valuable when working with expensive specialty polymers or developing new material formulations.
Scalable Performance: The modular design approach allows the Nexus to adapt to varying production requirements while maintaining research-grade precision. Whether processing small experimental batches or larger production runs, the system maintains consistent performance characteristics.
Beta Development and Future Vision
As we prepare for the beta launch of the Noztek Nexus, we’re committed to working closely with our research partners and customers to refine and optimize this groundbreaking technology. The beta phase will allow us to gather real-world feedback and fine-tune the system’s performance across diverse applications and materials.
